Jog my memory and remind me when exactly have I said that was the destiny Xe'ra wanted for him. Oh, that's right, I never said that. Because Xe'ra doesn't have the monopoly on chosen ones. Which I already made explicitly clear two posts ago:
You don't even know what you're arguing against at this point and, consequently, repeatedly drag the discussion back to a tangent that not only was never something I actually argued in favor of, but was outright denied by me. I'm not sure how that's supposed to work, but that's not exactly a solid basis for you accusing me of being wrong about lampshading.
Illidan became the jailer of a threat to the entire universe and as such its savior. That makes him a chosen one. Despite - stay with me here - that chosen one-ness >>>!!!NOT!!!<<< being what Xe'ra wanted for him. Because, it bears repeating, Xe'ra is not some kind of be all, end all of the chosen one trope.
And if that is supposed to be the supposed spiteful narrative about Saurfang of mine, then sorry, but that's just more of you being lost in the argument, because what we're discussing isn't "my spiteful narrative". I'm not the one who brought up Saurfang being sad (even though his sadness is the driving force of his entire story in this expansion and without it he'd be likely dead by now) nor the one who proposed him becoming the Night Warrior. Me addressing some of your concerns about the logistics of that when they make little sense in context of a deity that already forced changes on people in the past doesn't magically make that "spiteful narrative" mine.
Last time I checked the rule was "newer lore trumps older lore in case of conflict", not "newer lore creates a 'paradox' with older lore in case of conflict unless explicit explanation is given". What you're saying here is flat out wrong on all counts. If a character that died earlier in the story is seen alive later on, the very fact that they are alive retcons them dying. An explanation is not needed for that. There's no "paradox". Stories don't generally work on paradoxes unless the paradox is a deliberate choice in something like a time travel story. If it's not, the newest story bit changes the story if it conflicts with older story and as such retroactively changes the said older part. That's how retcons work and that's how they have always worked.
I mean, you're outright contradicting yourself here. If unexplained changes are bad forms of retcons then you admit they are retcons nonetheless. And if something can be a retcon without the explanation, even if it makes it a "bad form" of it, then that automatically means the explanation isn't a necessary element here. So thanks for shooting your own argument down. You totally validated your earlier allusions that I don't know what a retcon is right here.
A subjective improvement to the story doesn't negate the sloppy nature of storytelling fuckups that are retcons. Let's just use the example above. You thinking that the Eredar retcon "created a good deal more narrative fission and launched a compelling set of story-arcs all on its own" in regards to a race with no backstory (even though the same results could have been achieved without retconning anything) doesn't negate the fact that all of that has happened because Metzen simply forgot about what he wrote before. Even though at that point you wouldn't even fit one page with Eredar's previous story, making it a rather simple thing to fact check. And not remembering your own story and being unable to fact check it is sloppy, period. Especially in the scope we have in Warcraft.
And please, drop the fallacious appeal to passage of time. Because it's not like Blizzard retconning the shit out of everything is a new development caused by them simply being unable to follow the wealth of their established story by now. War of the Ancients trilogy retconned one of the biggest events in Azerothian history before WoW was even released, back when the entire story of Warcraft would have fit in a game manual. Blizzard retconning things isn't caused by them being feeble, oppressed and overwhelmed by the size of the material they work with. It's caused by them not giving a shit about the story and being to lazy to fact check anything. It's caused by them being motivated by making the next big flashy moment to satiate their rule of kewl obsession, everything else be damned. And somehow, despite those 20+ years, fans are somehow able to keep track of the story better than Blizzard time and time again and are the ones who point out those errors. Despite them not being the ones who get paid for writing the story.
Likewise, drop the straw-man (that you're not even employing for the first time) as well, because no one said anything about demanding no errors in 20+ years. Criticizing errors as sloppy isn't a demand, it's criticism. Conflating the two makes no sense. And errors are sloppy by default. That's what makes them errors. If a writer was paying more attention the error wouldn't have happened in the first place. And, as has been addressed a bit in a previous paragraph, there's a monumental difference between some errors in 20+ years and the mountain of fuckups that is Warcraft. Where even retcons get retconned. Either to other things or to the pre-retcon state of things. Even in regards to Chronicles which were supposed to set the story straight. Because Blizzard is simply incapable of keeping their story straight. Because that would actually take effort.
